Cardiorespiratory fitness (CRF):

Cardiorespiratory fitness (CRF) belongs to the capacity of the circulatory and respiratory systems to supply oxygen to skeletal muscle mitochondria for energy production needed during physical activity. CRF is an important factor of physical and mental health and academic achievement in youth. Cardiorespiratory endurance belongs to the ability of heart and lungs to work together to provide the needed oxygen, fuel and energy to the whole body during physical workloads. There are different examples of this type of physical workloads. During physical exercises like jogging, running, cycling, weight lifting and swimming, CRF refers to the ability of good working of heart and lungs. A healthy heart gives you definitely a strong, active and healthy body. When we define physical fitness, cardiorespiratory fitness comes at the most important components of fitness.

If there is no flexibility in the joints to move accordingly, we can’t say that the body is completely physically fit. Ability to perform certain functional movements such as the lunge and also stretching are the main examples of flexibility.
